lmtenteoi Application filed August 28, 1916. Serial No. 117,314.

To all whom it may; condor n:

l c it known that l, llAltRY ()Glum, a citizen of the lhiitcd States, residing at Yestbourne. in the county of Campbell and State of 'lennessce, have invented new and useful Improvements in 'lorpedwtatchers and Milie-Destroyers, of which the followin is a specification.

This invention relates to llllDl'OVQlllQlltS in torpedo catchers and mine destroyers for war ships, one objec of the invention being to provide an improved torpedo net arranged around the vessel and means to raise and lower the torpedo net as rerpiired; another objectbeing; to provide a mine destroying: apparatus which may be arranged at the bow of the vessel and employed for destroying mines" ahead of the vessel and which mine destroyer may also be renioved trom the vessel's how when desired.

l he-inventiou consists in the Features of construction, combination, and arrangement t devices, hereinafter fully described and claimed.

in the arcompanving drawings liigure l is an elevation of a. vessel provided with a torpedo net and also provided with a mine destroyer in accordance with my invention.

Fig. is a plan of the same.

Fifi. 3 is a rear elevation of the same.

Fin. 4 is a detail elevation.

Figs. 5 and (S are detail sectional views of the mine destroyer.

Fig. 7 is a detailed elevation of one of thrnet upporting devices.

The hull of a vessel is indicated at 1 and in arcordaiwe with nrv invention is provided on its sides and at suitable. spaced points with net supporting brackets! which are pivotally mounted as at 3 and are arranged to he turned outwardly from the vessel or swung inwardly against its sides as required. llarh bracket is provided with an outwardly extending net supporting arm l. and is also provided ith a brace 5 tor said arm.

'll a arm l is pivotally connected at its inner end as at i to a member t" which is secured on the vertical pivotal member ot the bracket. llenre the arm may be raised and lowered llltiiptlllltlltll oi the bracket, the latter being limited to horizontal pivotal movement. The bracket is provided at its upper corner with a rest 5 to receive the arm. The bracket with its independently the brackets.

pivotally mounted supporting arm is shown as at 7 and may also be swung outwardly from or inwardly against the sides of the vessel. A torpedo net 8 is stretched along the sides and across the stern of the vessel and has its upper side attached to the arms; of the brackets 2 as at 9 and has its front ends attached to the frames 6 as at 10. The. torpedo catching net is here shown as made of chains. It may, however, he made of any suitable material.

Rods 11 are arranged intermediate the brackets 2 and are bolted to the sides of the vessel as at 12. Hoisting links 18 are pivotally connected to said rods as at la and their outer ends are pivotally. connected to the upper side of the net at points between Hoisting means, suchtor stance as winches 15, are provided on the vessel and hoisting ropes 17 are attached to the outer ends of the links and also to the hoisting means and enable the netting to he raised or lowered as desired.

To swing the chain outwardly from the sides of the vessel, 1 provide cables 1'3 which are attached to the frames 6 and pass through suitable pulleys 20 and are connected to suitable winches or other like devices such as are indicated at '21. lVhcn these. cables are drawn the ends oi the not are pulled forwardly and hence the bracln eta the frame 6, and the intermediate supporting links are also swung forwardly and extended outwardly from the sides 015 the vessel thereof spacing the not from and around the vessel and stretching the net to enable it to successively withstand and catch tor ir-does and nevent the tort. .ioes from 111" 1 l A L I I ul-mg the, vessel. At the stern, opposite sides, I also provide stretching links which are, pivotallv connected to the Jesse sine Qi,

and are also connected to the upper the net.

The net may also, within the scope of my invention he provided with means for llOlSlh ing and arranging it ot the vessel to all'ord protection against air ships.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of construction and of the method of operatio'n will-he readily a pparentto those skilled in the art to which above the upper deck iii the invention relates, and while I have described the principles of operation of the device together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made when desired as are within the scope of the append ed claim.

Having described the claimed is: v

A. vessel, a supporting bracket pivotnily invention, what is mounted at one side of the vessel for horizontal angular movement to enable said bracket to be swung outwardly from or moved toward the side of the vessel, and at net supporting arm mounted for movement with the bracket and also for vertical pivotal movement, said arm being when lowered carried by said bracket.

In testimony whereof I ailix my signature.
